Inlet pipe fills the tank in 5 hr and outlet pipe empties the tank in 36 hr.
So inlet pipe is 36/5 = 7.2 times efficient than , ensure that the an outlet pipe.
Therefore , in order to tank never overflows , we will need total 8 outlet pipes.
Already we have 1 outlet pipe , thus we need only (8-1) = 7 outlet pipes

Inlet can fill tank in 1 hr = 1/5= 0.2
Outlet can empty tank in hr = 1/36 = 0.03
So
x*0.03 >0.2
(x is number of pipes)
So x= 8
